VILLIAM 7. S. ORBETON, OF LYNN, MASSACHUSETTS.

WINDOW-BLIND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 272,751, dated February 20, 1883.

Application tiled October 30, 1882. (No model.)

To all whom 'it may concern:

Be it known that l, WILLIAM V. S. ORBE- JEON, of L vnn,in the county ot' Essex and State of lllassachusetts, have 'invented a new and useful Improvement in Window-Blind Supports; and l do hereby declare the same to bedescribed in the following specification, and represented in the accompanying drawings, of which- Figurel is an edge elevation, and Fig.2aside view, ofthe lower portion of a blind, showing my invention or improved supports as applied thereto. Fig. 3 is a top view, Fig. 4 an edge view, and Fig. 5 a vertical section, ot' the supporter as separated from the blind. Fig. 6 is a transverse section of the shank of the supporter, showing the said shank as concave on its inner side.

The nature of my present invention is defined in the claims hereinafter presented.

On August 20, 1867, Letters Patent'No. 67,999 were granted to me for an improved hinge and blind supporter.7 My present invention relates to the kind ot' supporter so pat ented, and is to render such more effective in several respects. ln the patented supporter the screw-threaded body and its head or bearing-plate were inseparably connected; but in my improved supporter they are in two separate parts, one ot' which (the screw-threaded body E) is a common but long screw provided with a nicked head, h, while the other-that is, the bearing-plate o--has in it a c) lindro-conical recess, r, to receive the head of the screw, also cylindre-conical and titting closely in the recess, and has extending' rearward from it a tubular projection, t', through which the shank ot' the screw passes, such projection being to enter and fit into the blind-trame and to support the screw in its proper positionrelalively to the plate, the axis ot' the screw heilig usually a little less than a right angle to the plate, as shown in Fig. 5. l have found that by having the said cylindro-conieal recess in the plate c, and by having the screw-head cylindre-conical and to fit closely in such recess, the blind is better or stronger supported than would be the case were the screw-head conical and the plate countersunk to receive such head, though l sometimes so make them. I have also found" that when the screw is arranged at a slightly acute angle with the plate, as mentioned, better results follow than would be the case were the screw at right angles with the pla-te, for the blind is less liable to sag.

In the drawings, A denotes the aforesaid lower portion ot' the window-blind, and B is the supporter fixed thereto. G is the hingepintle carrier provided with the pntle or journal a, extending upward through the tubular hinge portion b, projecting` from the plate c of the supporter B. Besides the said tubular hinge portion the platechas extending hack from it, at a right angle to it, as shown, a lip, d, to rest against the outer surface ot' the blindframe, and to be connected to such frame by a screw going through the lip, in which is a counter-sunk hole, e, to receive the head and shank of the said screw. Furthermore, the plate chas projecting rearward from it a small point or stud,f, which, particularly When the supporter is without the hinge attach ment and the screw-holes gg at its upper part, enters the blind and aids in preventing the plate from accidentallyturning aside on the blind. I geilcrally hollow or make the plate slightly con cave on its inner side rather than dat, as in such case it tits at its edges to the blind.

The hinge-pintle carrier C, besides having a barbed and wedged point to enter the windowframe, has a right-angular extension, h', from it, as shown, provided with a point, i', to also enter the window-frame. The point or part i to enter the said trame, being in one piece with and at a rightangle to the rest of the extension, is not liable, as a screw lwould be, to work loose in the frame, and does not require the point to be driven to its full extent into the frame.

The blind-supporter binds together the side and bottom bars ofthe blind-frame, and thereby strengthens the frame, so as as to prevent sagging thereof and the consequent loosening of the slats.

To strengthen the part c, I usually arch or curve it transversely of it, and by having the screw E arranged at an acute angle, as shown, with such part c, the said screw, on being driven horizontally into the blind, so as to bend and press the part cinto close Contact IOC e 4 ere throughout its entire length therewith, produces in such part c a. force tending to press the screw upward in a mnnner to counteract or aid in counteracting the force tending` to sag the blind.

I do not herein claim a blind-supporter havingr its plate nud screw inseparably connected, as is the case with the.blind-supporter shown in the aforesaid patent, No. (57,999. With my improved blind-supporter its plate c cnn be let or bedded in the blind-frame, which sometimes has to be done; bnt when the plate and screwthrended body nre insepnrtibly connected such cannot be effected.

l/Vhat I clarin] is as follows:

1. The blind-supporter composed of the plate. c, provided with the tubular projection t', and of the sep-.irate headed screw E, zu ranged with such platte and projection as explained, nll beine for application to the frame ot' a. blind, in manner ns set forth.

2. The improved blind-supporter consisting ofthe plate 0, provided with the stud/and the tubular projection t', (ind of the separate screw E, arranged with such plate. and projection substantially as explained.

the barbed-wedge point and with the rightengnlnr and pointed extension, arranged as described, in combination with the blind-snpporter plate o, provided with the tubular extension to receive the pintle, Iill being' for application to a window and blind as explained.

6. The blind-supporter plate c, provided with the cylindre-conical recess r and tubular ex tension z'. in combination with the sep-.irate screw E. having n. cylindre-conical head to enter l.tnd tit the snid recess7 as explained.

7. The blind-supporter having its part c and its screw E arranged at an acute angle with each other. substantially as I(tud for the purpose set forth.
